GitHub - duolingo/rtk: CLI proxy that reduces LLM token consumption by 60-90% on common dev commands. Single Rust binary, zero dependencies

rtk is a Rust CLI proxy that filters noisy command output before it reaches an LLM.

Scope of this fork

This fork keeps output filtering and hook integrations, and removes:

• OpenClaw integration
• outbound telemetry
• outbound telemetry/call-home behavior; local rtk gain stats remain local-only

Install

Cargo

cargo install --git https://github.com/duolingo/rtk

Quick start

# Install hooks
rtk init -g

# Use filtered commands
rtk git status
rtk cargo test
rtk grep "error" .

Core commands

• Files: rtk ls, rtk tree, rtk read, rtk find, rtk grep, rtk diff
• Dev tools: rtk cargo, rtk npm, rtk pnpm, rtk vitest, rtk pytest, rtk go test
• Git/GitHub: rtk git, rtk gh, rtk gt
• Infra: rtk aws, rtk docker, rtk kubectl
• Passthrough: rtk proxy <cmd...>

Privacy

rtk in this fork does not send telemetry. Local rtk gain stats are stored only on disk and are never uploaded by RTK.
